IMPROVEMENT IN WHEEL-CULT|VATORS.

Specification forming part of Letters Patent No. 166,41 7, dated August3, 1875; application filed May 15, 1875.

To all whom it may concern:

Be it known that I, GEORGE W. So ENoK, of Geneva Lake, in the county ofWalworth and State of Wisconsin, haveinvented an Improvement inSulky-Oultivators, of which the following is a specification:

My invention relates to certain improvements in sulky-cultivators,having for its object to enable the rider to raise or lower either orboth plow-frames with one hand.

Figure l is a perspective view. Fig. 2 is a plan of the plow-frames andof the shield suspended between them. Fig. 3 is a partial elevation ofthe rear end.

In the drawing, A A represent the tractionwheels, each mounted on acurved or arched axle-arm, B, both arms being bolted to the under sideof an axle-beam, B, on top of which the rear ends of a split or forkedtongue, 0, are bolted. D is a seat for the driver on a perch projectinghorizontally to the rear of the axle-beam. E E are the main beams of theplow-frame, each hung by a pair of eyebolts at the front end to theunder side of the draft-tongue. E is a shorter beam at the inner side ofeach beam E, and is hinged thereto at the front end by a pin through aplate, a, projecting inwardly from the latter. An arched bar, F, is laidacross all the beams, its flat or straight ends passing underclampplates b on the outer beams, and under similar ones, I), on thebeams E. A plow-standard (and shovel) is placed on each side ofeach beamE, and one on the inner side of each beam E. The outer shovels areadjustable as to the distance between them by moving their beams to therequired distance apart, and then securing them in position by screwingdown the bolts through the clamp-plates b. The inner beams may in likemanner be adjusted and secured, if desired; but in practice they willnot be clamped to the gage-bar F, being free to move laterally. Theirpositions will be under the control of the driver, who sits with a footresting upon the rear end of each beam E, so that he can move it towardor away from the straddled row by a movement of the foot, ascircumstances may require.

G is an arched metal shield, hung by a flexible metal strap, G, at thefront end, to the under side of the tongue, while its rear end issuspended between the shovels and directly over the straddled row by twowires or cords from the bar F. Its office is to protect the young cornfrom injury from dirt thrown too close to or upon it by the innershovels.

The plow-beams are raised and lowered in the following manner: A shaft,H, is journaled through bearings 0 across the rear ends of the forkedtongue, with an arm at the lefthand end, to which is attached one end ofa cord, I, or chain, passing over a sheave in a standard, J thence downto the left hand shovel-beam E. At the right-hand end there is a lever,K, having a gripe spring-pawl, d, which engages with a notched quadrant,e, projecting to the rear from the right side of a standard, J. By meansof this arrangement of devices the left beam may be raised and loweredand suspended at any point of elevation. K is a similar lever, havingapawl, 61, which engages with a quadrant, e, at the left side of thestandard J, and from which a chain passes over a sheave in saidstandard, and down to the right beam E. The lower end of said lever K issleeved upon the shaft H, and by means thereof the said beam E may beraised and lowered at will.

The levers are so near together that they may be simultaneously drawnback to lift both sets of shovels in case a large obstruction is metwith.

i What I claim as my invention is- In a cultivator, substantially asdescribed, the combination of the levers, K for lifting each set ofshovels, both placed at one side of the frame, one being rigidly securedto a rockshaft, and the other turning independently of said rock-shaft,so as to be used separately or to be simultaneously drawn back by onehand,

substantially as described and shown.
